Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pine surgery device that can perform pine surgery on a user's entire body.

Generally, the above-mentioned pine surge device has a pair of guide rails installed along the longitudinal direction on the upper surface of the base, and a pine surge roller is provided so as to be freely movable along the guide rails. The pine surge roller is dismounted so that it can be moved back and forth along the length of the substrate by a drive. Therefore, when the user lies face up on the pine surge device, the user can receive pine surge all over the body by the pine surge roller.

By the way, the above drive device conventionally includes a drive source disposed at one end in the longitudinal direction of the base, a first pulley rotationally driven by the drive source, and a second pulley disposed at the other end in the longitudinal direction of the base. A pulley, and a wire stretched between the first pulley and the second pulley. The pine surge roller is indirectly connected to the wire, and when the wire is moved by the rotation of the first pulley, the pine surge roller is interlocked. However, if the pine surge roller is driven by a drive device with this kind of structure, slippage will easily occur between the wire and each pulley when the user's load is applied to the massage roller, so it is difficult to ensure that the pine surge roller is driven properly. There were times when it would not be driven. Also,
If the tension of the wire is increased to reduce slip between the wire and the pulley, a problem arises in that the power loss of the drive source increases.

The present invention has been made based on the above circumstances, and its purpose is to provide a pine surge device that allows the pine surge roller to run reliably even when a user's load is applied to the pine surge roller. It's about doing.

There is. The running direction of the belt 5° is changed by approximately 180 degrees by the support pulley 22, and then passed through the opening 24 formed in the guide rail 8 and into the lower passage 15. At the location of the opening 24, the belt 50
The running direction is slightly changed by the pitching roll 2o. The other end of the belt 5o led out from the lower passage 15 is wound around the second driving pulley 4o and the third driving pulley 42, respectively. Therefore, when the first driving pulley 37 and the second driving pulley 4o or the third driving pulley 42 and the fourth driving pulley 44, which are paired with each other, are rotated in opposite directions, The belt 50 is wound around one drive pulley,
The wound length is fed out from the other pulley.

For example, in FIG. 5, when the first driving pulley 37 is rotated in the direction of the arrow X and the second driving pulley 40 is rotated in the direction of the arrow Y, the portion of the belt 50 inserted into the upper passage 14 is rotated in the direction of the arrow 2.

@The third support 53 is screwed through 9.
As shown in the figure and FIG. 11, a pair of wheels 6θ are rotatably provided by a support shaft 61. As shown in FIG. This wheel 60 runs on the guide surface 16 of the guide rail 9. Above support shaft 6
One end of 1 has an inverted T in cross section as shown in Figure 3.
One vertical side of the shaped connecting member 62 is attached and fixed.

The other horizontal side of the connecting member 62 is fixed to a portion of the belt 50 that is inserted into the upper passage 14. That is, one vertical side of the connecting member 62 is led out from the gap between the pair of L-shaped pieces 13 forming the upper passage 14 and is fixed to the support shaft 61. Therefore, the holding body 51 is connected to the belt 50 by the connecting member 62, and is interlocked with the running of the belt 50. Further, a plate member 65 is attached to the other end of the support shaft 61, and the lower end of the plate member 65 is bent at a right angle and inserted into the locking portion 11 of the guide rail 9. In addition, the hollow shaft 52
Four collars 66 are provided in a rotatable manner without shifting in the axial direction. A pine surge roller 267 is attached to each collar 66. The pine surge roller 67 is made of a relatively hard elastic material such as rubber or synthetic resin, and has a large number of approximately hemispherical protrusions 68 on its outer peripheral surface. are provided protrudingly at predetermined intervals in the circumferential direction. A stopper 69 is provided on the outer peripheral surface of each collar 66 to prevent the pine surge row 267 from shifting in the axial direction of the collar 66.

On the other hand, the running direction of the belt 500 is controlled by a control device 70 provided inside the case 31 of the drive device 30. This control device 70 includes a plate-shaped body 71 as shown in FIGS. 12 to 14. The plate-shaped body 71 is fixed to the first mounting shaft 38 which is pivotally supported on the mounting plate 33 inside the case 31 by a set screw 72.

Furthermore, a spiral first guide groove 73 and a second spiral guide groove 74 are formed as guide portions on both side surfaces of the disc-shaped body 71, respectively. A first step 75 and a second step 76 are provided in a portion of each guide groove 73,74, respectively, to make the guide groove 73,74 shallower than other portions. First step 75
is provided at a position R1 in the radial direction from the rotation center 0 of the disc-shaped body 71, and the second step portion 76 is provided at a position R2. R1 is also larger than Rg. Therefore, the first step portion 75 is located radially outward from the second step portion 76 by a plurality of turns of the guide groove. Further, a pair of support pieces 77 are provided protruding from the mounting plate 33 near the plate-shaped body 71, and a support shaft 78 is provided on the support pieces 77. This support shaft 78
Seven frames 79 each having a C-shaped cross section are pivotally mounted at one end. Band-shaped leaf springs 80 are provided on both outer surfaces of the frame 79, with their ends fixed to each other. A shaft-shaped body 81 is provided protruding from the other end of the leaf spring 8'0.

This shaft-shaped body 8 is bored on both sides of the frame 790 by the biasing force of the leaf spring 80, and protrudes from the nine-through hole 82 to the inner side of the both sides. Furthermore, a first limit switch 83 and a second limit switch 84 are provided on both outer surfaces of the frame 79, respectively, and are fixed to a plate member 85.

These limit switches 83 and 84 are actuated by these leaf springs 80 when the other end of the leaf spring 80 is elastically deformed in a direction away from the outer surface of the frame 79. The frame 79 is a plate-shaped body 7 as shown in FIG.
1, and the pair of shaft-like bodies 81 are tilted in the first direction.
It is engaged with the second guide grooves 73 and 74. ·and,
When the disk-shaped body 71 rotates as described later, the shaft-shaped body 81 moves relatively in the guide grooves 73, 74, and the shaft-shaped body 81 moves into the first step 75 or the second step 75.
When the plate spring 80 is displaced by the stepped portion 76, the leaf spring 80 is elastically deformed. Also, the above Rimi Tosui f83.84
is electrically connected to the drive source 34 of the drive device 30, and controls the rotational direction of the output shaft 35 of the drive source 34. That is, when the output shaft 35 is rotated clockwise, for example, the first limit switch 83
When the output shaft 350 is activated, the rotation direction of the output shaft 350 is changed counterclockwise. Further, if the second limit switch 84 is actuated while the output @35 is being rotated counterclockwise, the rotation is converted clockwise.

On the other hand, on the upper surface of the base 1, a wall member 9o is provided on the outside of the pair of guide rails 9 and at one longitudinal end of the base 1, as shown in FIG. The ξ wall member 90 is covered with an exterior sheath 91 made of a bendable elastic material, such as urethane foam.

Note that the drive device 30 can be remotely operated using a switch (not shown).

Next, the case where the pine surgery device having the above structure is used will be explained. First, the pine surge device is placed on the pine tress 95 as shown in FIG. 16, and this pine tress l;
The user lies face up. Then, since the base body 1 and the guide rail 97 of the pine surge device are made of flexible materials, they will cause the irregularities on the back of the user to change. The driver operates the driver to activate the drive source 34 of the drive device 30.

This drive source 34 operates and the output shaft 35 moves as shown by the arrow X in FIG.
When rotated clockwise as shown by , the first pulley 37 and the fourth
pulley 44 rotates in the same direction, and the second pulley 40 and third boolean 942 rotate in opposite directions. therefore,
The pair of belts 50 are wound around the first pulley 937 and the fourth pulley 44, respectively, and the second pulley 40 and the third pulley 4 are wound around the second pulley 40 and the third pulley 4 according to the wound length.
2, the portion of the belt 5o inserted into the upper passage 14 of the guide rail 9 runs in the direction shown by the arrow 2 in FIG. When the belt 5o runs in this way, a pair of holding bodies 51
are interlocked, so that the plurality of pine surge rollers 67 provided on the hollow shaft 52 of the holder 5 travel while rotating in the direction shown by arrow S in FIG. 11 due to contact with the inner surface of the exterior material 9. The protrusion 68 presses the back of the user.

On the other hand, when the output shaft 35 rotates in the direction of the arrow X, the first mounting shaft 38 rotates in the direction of the arrow Y, and the control device 7
0 disk-like body 71 is interlocked.

When the plate-like body 71 rotates in the direction of arrow Y, this plate-like body 71
1st. The shaft-like bodies 81 respectively engaged with the second guide grooves 73, 74 move relatively along the guide grooves 73, 74, and the frame 79 rotates in the direction shown by arrow T in FIG. Then, due to the rotation of the plate-like body 71, one shaft-like body 81 engaged with the first guide groove 73 is moved to the first step portion 75.
When it is displaced in the direction of protruding from the first guide groove 73, one of the leaf springs 8 to which this shaft-like body 81 is attached
0 is elastically deformed as shown by the chain line in FIG. 14 and operates the first limit switch 83. Then, the rotation direction of the output shaft 35 of the drive source 34 is changed by the signal from the first limit switch 83, so that the running direction of the portion of the belt 50 inserted into the upper passage 14 is opposite to the direction of the arrow 2. It's funny. Therefore, since the pair of holders 51 are interlocked with the running of the belt 50, the pine surge roller 6
7 causes the user to be pine-surged. Further, at this time, the plate-shaped body 71 rotates in the opposite direction to that previously, that is, in the opposite direction to the arrow Y, so the frame 79 rotates in the opposite direction to the arrow T direction. Then, when the other shaft-shaped body 81 engaged with the second guide groove 73 is displaced by the second step 76, the other leaf spring 80 to which this shaft-shaped body 81 is attached is moved to the 14th
As shown by the chain line in the figure, it is elastically deformed and the second limit switch 83 is activated. Then, since the rotational direction of the output shaft 35 of the drive source 34 is changed by the signal from the second limit switch 83, the running directions of the pair of holders 51 become two directions again.

As shown, the pair of holders 51 are reciprocated over a distance corresponding to the rotational speed of the plate-shaped body 7 when the first limit switch 82 or the second limit switch 83 is activated. .

Further, when the pine surge device is not in use, it can be folded into two from the central portion in the longitudinal direction of the base body 1, as shown in FIGS. 17 and 18. That is, the base 1
Since the longitudinal center portion of the guide rail 9 and the guide rail 9 are formed into a bendable first flexible portion 7 and a second flexible portion 18, respectively, the base body 1 and the guide rail 9 are connected to the base body 1.
It can be folded into two together with the wall member 9o provided on the top surface. Therefore, the length of the pine surge device can be reduced to about half when not in use, making it convenient for storage.

Further, the guide rail 9 is fixed to the base body 1 only at one end in the longitudinal direction. Therefore, the guide rail 9
When the guide rail 9 is folded together with the base body 1, the other side slides freely, so that when the guide rail 9 is bent, a large bending stress is not generated and the guide rail 9 becomes difficult to bend.

In this embodiment, the sill 1 may be formed only by the second part. Further, the power transmission strip may be a chain, a wire, or the like in addition to a belt.

As described above, the present invention provides a pair of drive pulleys that are driven to rotate in opposite directions on one longitudinal end of the base, one end of the power transmission strip is wound around one of the drive pulleys, and the other is wound around the other end of the drive pulley. While winding the end portion, the middle portion was hung on a support pulley provided on the other end side of the base body, and a pine surge roller was connected to this power transmission strip. In other words, the power transmission strip is wound around one driving pulley and is sent out from the other driving pulley to travel, so even if the user's load is applied via the pine surge roller, , No slip occurs between the power transmission strip and each pulley. Therefore, since the pine surge roller is reliably driven by the power transmission strip, the user can receive good pine surge all over his/her body from the pine surge roller.
